EYEGLASS-FRAME.

Specification of Letters Patent.

Application filed iTune 4, 1910. Serial No. 565,038.

It is the object of this invention to provide an eye glass frame so constructed that the lenses may readily be removed from and inserted intothe frame, the device being so '-(.'OIlStI'U(3te(.l that the lens will be rigidly and securely held in place without engaging the lens by a screw or the like, the adjustmentof which might result in a breakage of the lens.

In the drawings, Figure 1 is an elevation,

. darts bein broken awa Fi 2 is a fra P. 7 8' b mental transverse section: and, Fig. 3 is a detail perspective of portions of the device. -The invention includes, as a primary and fundamental element an arm 1 )rovided at one end with an outstanding stud 2,

adapted to be received in a suitable opening adjacent the periphery of the lens 3. Adjacent the other end of the arm 1 there is a rectangularly disposed extension 5 from the end'of which extends transversely of the arm 1, a resilient, arcuate strip 4, the ends of which bear against the periphery of the lens 3 to press the lens against the stud 2. There are fingers 100 at the ends of the strip 4 to overlap the lens 8. Agaii'ist. the end of this extension 5, the'connecting spring 6 between the lenses 3 rests, the face plate 7 the stud 2', serves to hold the lens 2,

being superposed upon the spring 6 and the spring (land the face plate 7 being secured to the extension 5 by means of a screw or the like. To the face plates '1' the clips proper 9, commonly fashioned from cork or celluloid are secured.

The device further includes a slidably n'iounted member,which, cooperatingwith in place against displacement from the frame. This slirlably mounted member consists oi a plate 10, having an elongated opening '1 l. A screw 12 is mounted in this opening ll and threaded into'the extension 5 of the arnrl, the plate 10' sliding upon the screw 12. The

slot 11 :in the plate 10 is of sufficient length to permit the plate 10 to slide upon the screw 12 until, as shown in Fig. 1, the end of the stud 2 is located within the contour .of the slot 11. The plate 10 is resilient and bears yieldingly against the lens 3. By permitting the end of the stud 2 to come within the contour of the slot 11, the lens 3 may be held securely .in place, even though the stud 2 should be somewhat longer than the thiclc,

noss of the lens 3, a construction seen most clearly in Fig. 2. Thus, should the stud 2 be somewhat longer than the thickness of the lens, it is not necessary to file the stud down in order that theplate 10 may have a bearing against the lens 3.

When the plate 10 has been slid into the position shown in Figs. 1 and 2 of the drawifi'gs, the screw 12 may be tightened so that the head 14 thereof will bear against. the plate 10, thus holding the plate in place against sliding movement. If desired, for convenience in -m-.u1ipu1ating the plate 10, the same may be provided at its inner end,

with an outstanding arm 1-5, adapted to heengaged by the finger of the operator.

Having thus described the invention, what is claimed is .v

1. An eyeglass frame having means to engage a lens; a slotted member; and a supporting device locaited-in' the slot of said member and engagin the frame, upon which supporting meni er the slotted member is adapted to slide to cooperate with said means to hold the lens against displacement, the supporting member being ma'nipulable to retain the slotted member against sliding movement.

2. An eye glass frame including an arm having a stud at one end adapted to be inserted into a. lens; slotted plate slidable upon the arm and cooperatingwith the stud to hold the lens agaii'ist displacement; and a set screw located within the slot of the plate and engaging the arm to constitute a mounting for the plate," and to constitute a. means for holding the plate against movci'nent.

In testimony that I claim the foregoing as my own, I have hereto affixed my signa ture in the presence of two witnesses.
